How To Use Chlorothalonil DF Fungicide

  • Square footage is calculated by taking the length of a given area and multiplying it by its breadth. Using the formula: (square footage / 43,560) x (decimal) = (acres), we may calculate the total area of a given plot of land. Using Chlorothalonil at a rate of 1 to 2.5 pounds per acre in 100 gallons of water is standard practice. To treat an area measuring 3 acres, for example, you would combine 3 to 7.5 pounds of product with 300 gallons of water. The prevalence of a condition and the location of an application both impact the number of applications received.
  • To use, calculate how much Chlorothalonil DF you will need, then add half that amount of water to your spray tank. To achieve a thoroughly blended final result, add the remaining water and give it a good stir.
  • Don’t stop the blending process while you’re in the middle of filling out forms. To get the best results, your applications should be consistent and complete. Disease suppression and plant health are prerequisites for re-treatment applications.
  • There must be an untreated buffer zone of at least 150 feet wide between the area to be treated and any marine or estuary water bodies for aerial and air-blast applications, or 25 feet wide for ground applications.

At all times tank mixes Quali-Pro Chlorothalonil DF with a fungicide of a different chemistry, and/or alternative applications of a fungicide of a different chemistry and Quali-Pro Chlorothalonil DF to prevent the evolution of tolerant or resistant populations of fungi.

We do not recommend using Chlorothalonil DF Fungicide on residential lawns. We advise using Martin’s Systemic Fungicide RTS to treat lawns and gardens for a wide range of fungal infections.

If the treatment does not work after following the instructions for using Quali-Pro Chlorothalonil DF, a tolerant or resistant strain of fungi may be present. Forego using Quali-Pro Chlorothalonil DF during the upcoming growing season.
